How to use Best Free Image Converter?

Just 3 steps!


Step 1: Add Source Files. 

How to use Best Free Image Converter - Step1

Click the button in the tool bar of "Add Source Files", select the image files to be converted, or directly drag the image files from folder to the source file list.

Step 2: Set conversion Options and preview conversion effects.

● Select an image in the source file list, and the image will be displayed in the preview area on the right side of the interface. You can choose "Source", "Effect", or "None". When the preview image is "Effect", set any option to display the conversion effect immediately.

● Select the folder of converted images to be saved in.

● Select the color of the output image: There are 8 color options, such as Black & White, Gray, and True color, to realize the conversion from color image to black and white, gray image. It is recommended to choose "True color" for general color pictures.

● DPI setting: If you want the output picture to have a specific DPI value, check the "DPI" item and set the DPI value. If "DPI" is not checked, the software will output according to the DPI value of the source image. Note: The higher the DPI value, the clearer the picture will be when printing. For example, printing a picture requires 300 or more values, which will be clearer. The average network picture is 72.

● Select the output image format: 14 output formats are provided, including PDF, PS, DCX, TIFF, which can combine multiple images and output them into one file. JPEG, PNG, JPEG2000 and other compressible graphics formats can compress images according to their own needs. Note that the more compressed images, the smaller the file size, but the worse the image quality. You can also select "original format" as the output format. For example, if the source file is PNG format, the converted format is also PNG format. If the source file format is not within the 14 output formats, it will be uniformly converted to JPEG format.

● Resize or rotate the images if needed. You can select the sub-option of "Scale" or "Input Value" under the option of "Resize". You can also rotate the picture 90, 180, and 270 degrees, and mirror it horizontally or vertically.

Step 3: Start Convert. Click the “Start Convert” button.
